TYPE-CLEANER FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 766,786, dated August 2, 1904.

Application filed January 2, 1903.

To all whom it may concern:

Be it known that I, AUGUSTUS Mormon WING, a citizen of the United States, and a resident of Spokane, in the county of Spokane and State of "Vl' ashington, have invented a new and Improved Type-Oleaner for Type- VVriting Machines, of which the following isa full, clear, and exact description.

The invention relates to type-writing machines of the class having type-bars arranged in basket form; and its object is to provide a new and improved type-cleaner for type-writing machines which is simple and durable in construction, very effective in operation, easily applied to the different makes of circular type-writing machines, and arranged to insure a perfect cleaning of the type without danger of injuring the same.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional front elevation of a circular type-writing machine to which the improvement is shown applied. Fig. 2 is an enlarged sectional front elevation of the improvement. Fig. 3 is a sectional perspective view of the same, and Fig. A is a sectional elevation of a modified form of the brushmounting.

A support A, preferably in the shape of a horizontally-disposed bar, is secured to the sides B of the frame of a type-writing machine having its type-bars arranged in basket form, said bar extending between the front and rear connecting-rods of the key-levers at each side, and on the said support A is mounted to move sidewise a slide O, extending to one side of the machine to be within convenient reach of the operator to enable the latter to move the slide in or out for the purpose hereinafter more fully described.

On the inner end of the slide O is pivoted a Serial No. 137,384. (No model.)

brush-post D, in the free end of which screws a pivot E, on which is mounted to turn the back F of a brush F, preferably made in the shape of an inverted truncated cone,as plainly indicated in the drawings, and the said post D is pivotally connected by a brace or link I) with the support A, so that when the slide G is moved inwardly the brush-post I) and brush F swing downwardly out of the path of the types G or the type-bars G, as indicated in dotted lines in Fig. 1, and when the slide O is pulled outward then the brush-post D swings upward and carries the brush F centrally up in the basket of the type-writing machine, so that the types G can movein engagement with the sides of the brush-that is, With the ends of the bristles on the operator actuating the keys of the type-writing machine in the usual manner that is, causing the type-bars G to swing upwardly from their normal resting position until the types G strike against the ends of the bristles. Now it will be seen that the types-G stand at a distance from the tapering side of the brush F when the latter is in an uppermost central position within the basket, so that when a key is pressed the corresponding type-bar G swings upwardly, and thus moves the type G in forcible contact with the ends of the bristles, so that the ink and other liardened matter on the type is readily dislodged and removed and the type cleaned to insure a good impression when the machine is in use for its legitimate purpose. hen the several types are cleaned by successively actuating the keys as mentioned, then the operator simply imparts an inward-sliding motion to the slide C, so that the brush F moves straight down through the central opening formed by the types G without coming in contact with the latter, and when the brush is in a lowermost position it is completely out of the path of the types G, so that the machine can be used in the usual manner for type-writing purposes.

The post 1) and its brace 1) are preferably provided with wings D and 1D", resting on the slide O and support A, respectively, at the time the post D is in a vertical position, so-

that the post is firmly supported to hold the brush F in proper position for engagement by the types G. The brace D extends through an elongated slot C in the slide C to connect with the support A.

In the modified form of the brush-mounting shown in Fig. 4 the upper end of the brushpost is formed into a pivot D*, on which is mounted to turn the hub F secured to the brush-back F, the lower end of the hub F resting on a collar D formed on the brushpost D. The brush F is held against displacement on its pivot D* by a screw E, screwing in the said pivot D and extending with its head on the brush-back, as plainly shown in Fig. 4.

The bristles of the brush F extend approximately in the line of movement of the types G, so that on actuating a type-bar Gr its type G strikes the ends of the bristles without unduly bending the same, and hence the bristles act very efiectively on the type for cleaning the same of extraneous matter. The impact of the type on the ends of the bristles causes the brush to revolve, so that the same type when its type-bar is repeatedly actuated does not strike the same but different bristles, and as the brush revolves it tends to brush the type sidewise. Hence a very effective cleaning of the type is the result. As the ends of the bristles are very fine, they readily enter and dig out extraneous matter that lodges in the types at the time a type is forced up against the endsof the bristles.

The device is verysimple and durable in construction and can be readily placed in position on any circular or basket type-writing machine, and the brush can be instantly moved into an active position within the basket or moved into an inactive position out of the path of the types by the operator simply shifting the slide C correspondingly.

. Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A type-cleaner for type-writing machines, comprising two horizontal members slidable one upon the other, a swinging brushsupport carried by one member, a brush revolubly mounted on the support, and a link connection between the brush-support and the other member, as set forth.

2. A type-cleaner for type-writing machines, comprising a pivoted support, a brush revolubly mounted on the free end of the support and adapted to be revolved by the impact of the type against the face thereof, and means for moving said support into a vertical or inclined position, as and for the purpose set forth.

3. A type-cleaner for typewriting machines, comprising a pivoted support, a brush carried by the support and having its bristles extending approximately in the line of movement of the type, and manually-controlled means for moving the support into a vertical position in the basket with the brush spaced from the type-bars for the type thereof to strike against the face of the brush on actuating the keys, the said means also serving to move the support into an inclined position with the brush out of the path of the typebars, as set forth.

4:. A type-cleaner for type-writing machines, comprising a bar, a'slide thereon, a toggle connection between the bar and slide,

and a brush carried by one member of the.

toggle connection, as set forth.

5. A type-cleaner for type-writing machines, comprising a support, a slide thereon, a brush, and a post carrying the brush and having a pivoted brace, the said post and its brace being pivotally connected the one with the support and the other with the said slide, as set forth.

6. A type-cleaner for type-writing machines, comprising a support, a slide thereon, a brush, and a post carrying the brush and having a pivoted brace, the said post and its brace being pivotally connected the one with the support and the other with the said-slide, the said post and its brace having wings, adapted to engage the support and slide, as set forth.

7. A type-cleaner for type-writing machines, comprising a support, a slotted slide thereon, a post pivoted to the slide, a brush carried by the post, and a brace having one end pivoted to the post and its other end extending through the slot of the slide and pivoted to the support, as set forth.

8. A type-cleaner for type-writing machines, comprising a support, a slide mounted on the support and provided with a longitudinal slot, a post pivoted to the slide, a conical brush revolubly mounted on the upper end of the post, and a brace having one end extending through the slot of the slide and pivoted to the support and its other end pivoted to the post between its ends, as set forth.

9. A type-cleaner for type-writing machines, comprising a support, a conical brush revolubly mounted on the support and adapted to be revolved by the impact of the type against the face thereof, and means for moving the brush into and out of the path of the type.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
